The actor - who played the president in the film Deep Impact - gave the seven-figure sum to the Obama super PAC Priorities USA Action - which finances advertisements for the re-election campaign.

In a statement on politico.com, Freeman said: "President Obama has done a remarkable job in historically difficult circumstances. He ended combat operations in Iraq, put in place sensible reforms of Wall Street, saved the auto industry and protected the health care of every American."

He added: "I am proud to lend my voice - and support - to those who defend him. Priorities USA Action is doing a great job of protecting the values I believe in. I am happy to help them and I hope others will join me."
